“Look, one day I had gone to a little village. An old grandfather of ninety was busy planting an almond tree. ‘What, grandfather!’ I exclaimed. ‘Planting an almond tree?’ And he, bent as he was, turned around and said: ‘My son, I carry on as if I should never die.’ I replied: ‘And I carry on as if I was going to die any minute.’

While 'as if I will die tomorrow' is pretty much the same, but as a positive this time as in death is a certainty so always prepped for it.

Second one puts too much emphasis on death.

Personally they're both wrong imho, best depiction of life/death I've ever seen was in the Ubihole game Dark Messiah, life is a dance, some merely perform the steps for longer than others, some attempt to dance while never quite getting footwork down and before they learn the music stops for them etc etc.

Death is indeed always around the corner, it is the absence of life of music, not at all something that should be feared or reviled, or any pay heeded to it (not to the point of total ignorance, nothing pisses me off more than people saying death is a tragedy, most absurd concotion of the modern/early modern era).
